The UI introduction will be a series of short guide showing new players how to navigate the game. Well obviously there'll be the tutorial when you first start out the game, but that should be pretty much a no brainer. Just play through it and follow their prompts. After that, you'll be on your own.

To start off the UI introduction, I'll begin with the main info page. It's the very first thing which will pop up after you logged into the game.

It has been a long while since Puzzle and Dragons was released in Japan. I've no idea how its US counterpart is doing, but PaD's success in Japan was never quite matched by any other apps in the region. And honestly speaking, there's no apps which has captured my attention like how PaD did for such a long period of time.
